Fault codes are only available when an OPm2 is connected to the CombiDrive

®

.

In the event of a failure, the CombiDrive

®

 switches off and a fault code appears on the LCD screen. The last

fault that occurred is stored in parameter P930. e.g. ‘0003' indicates that the last error was F003.

Overvoltage

Check whether supply voltage is within the limits indicated on the rating plate.
Increase the ramp down time (P003).
Check whether the required braking power is within the specified limits.

Overcurrent

Check motor lead and motor for short-circuits and earth faults.
Increase the ramp-up time (P002).
Reduce the boost set in P078 and P079.
Check whether the motor is obstructed or overloaded.

Overload

Check whether the motor is overloaded.

Overheating of motor
(monitoring with PTC)

Check if motor is overloaded.
Check the connections to the PTC.
Has P087 been set to 1 without a PTC being connected?

Inverter overtemperature
(internal PTC)

Check that the ambient temperature is not too high.
The motor speed may be too low for a given load.

Power module overtemperature

Check that the ambient temperature is not too high.

USS protocol timeout

Check the serial interface.
Check the settings of the bus master and P091 - P093.
Check whether the timeout interval is too short (P093).

Undervoltage

Check that the power supply is supplying enough voltage to the inverter.

Initialisation fault / Parameter loss *

Check the entire parameter set. Set P009 to `0000' before power down.

Internal interface fault *

Switch off power and switch on again.

External trip

Source of trip is digital input (configured as an external trip input) going low -
check the external source.

Programme fault *

Switch off power and switch on again.

Auto restart after fault

Automatic restart after fault (P018) is pending.
WARNING:  The motor shaft may start to rotate at any time.

PROFIBUS link failure

Check the integrity of the link.

Option module link failure

Check the integrity of the link.

PROFIBUS configuration error

Check the PROFIBUS configuration.

PROFIBUS module watchdog trip

Replace PROFIBUS module

Motor overtemperature by I

2

t

calculation

Check that the motor current does not exceed the value set in P083.

Parameter fault P006

Parameterise fixed frequency(ies) and/or motor potentiometer on the digital
inputs.

Parameter fault P012/P013

Set parameter P012 < P013.

Digital input parameter fault

Check the settings of digital inputs P051 to P053.

P006 = 1 while P201 = 2

Change parameter P006 and/or P201.

Parameter fault P211/P212

Set parameter P211 < P212.

When the fault has been corrected, restart the inverter and the motor will run if the fault has been cleared.
